Is it possible to ignore specific warnings with Visual Studio Code's linter?

Question

Our company is thinking about switching from Sublime to Visual Studio Code.

With SublimeLinter it's possible to use ignore_match statements in the preferences file to ignore specific warnings. This lets us hide false positives such as tracking tags in URLs.

I've tried to find an equivalent function in VSC but to no avail. Can anyone tell me if this can be achieved?

Thanks

I think that your linter's configuration is going to be very language specific - this is an answer for Golang, and it's probably going to be very different depending on the language you're using.

Working with Golang in VSCode, you can set the linter that you use. There are several choices, including (as of 2018-10-31) gometalinter. gometalinter provides the --exclude flag that can be used to ignore specific warning text.

For example, my current project has the following warnings from golint:

> golint ./...

cmd/launch_provider_instance.go:40:2: don't use ALL_CAPS in Go names; use CamelCase
cmd/launch_provider_instance.go:241:6: func Foo should be FOO

If I change my VSCode Go Linter settings to be this:

{
    ...
    "go.lintTool": "gometalinter",
    "go.lintFlags": [
        "--disable-all",
        "--enable=golint",
        "--exclude=exported (const|type|method|function) [\\w.]+ should have comment (\\(or a comment on this block\\) )?or be unexported",
        "--exclude=don't use ALL_CAPS in Go names; use CamelCase",
        "--exclude=(func|const|struct field|) \\w+ should be \\w+"
    ]
}

Then all of the warnings I was seeing earlier are squashed. To read more about gometalinter, check out the main GitHub page of the project.
